Hi, there is already a stuff trading thread in discord, but no free offer.
NB. I understand if you do not like it, as for the gameplay reasons you may see it as a game spoiler, so just do not read this. However in an immersive roleplaying one can imagine the Survivors after the robot apocalypse invasion could be helpful one
to another 
Edit:
So,
if anybody wants I can offer (not exchange) a golden Moller PP mag and a golden shotgun silencer.
